The object of this paper is to give experimental data on atmospheric absorption as it affects the measurements of the radiation constants. The paper gives also a recalculation of the coefficient of total radiation of a uniformly heated enclosure, taking into consideration all losses by reflection from the receivers, as well as losses by atmospheric absorption. The value of the coefficient obtained is ? = (5.722±0.012)×10/sup -12/ watt cm./sup -2/ deg./sup -4/, which is the same as previously...

Contains the results of an investigation during which the Brinell hardness was determined for five steels varying in carbon content from 0.07 to 1.12% after heat treatment arranged to produce wide variations in grain size. Upon heating for 6-hour periods no very appreciable increase in grain size occurs until the Ac transformation has occurred. The change in grain size often appears to be a very abrupt one, taking place within a narrow range of temperature. Two methods were used for obtaining...
The sulphur boiling point occupies a position of unusual importance among the thermometric fixed points on account of the care and accuracy with which its temperature has been determined, the precision with which this temperature may be reproduced, but most of all on account of the very general practice of using it to determine one of the fundamental calibration constants of the platinum resistance thermometer, which serves as the most precise and convenient means now available for defining the...
